Before Max left the hangar, he sent a message to the Enovys with the technical details of the new weapons, in case they hadn't already gotten a copy of them, as well as the humans' regulations on their use against populated planets.
There weren't actually any rules against using them on ships, but Max realized that the Alliance would certainly have something to say about that since they used a large number of vessels with populations in the millions, which a single antimatter missile could theoretically destroy.
This was far from the first time that he had been required to attend the "Humans did WHAT?" conversations, but they were never a lot of fun, and it was mostly technical matters that he really wasn't experienced in, so he was basically reading them to his audience as he learned them.
